Question

Tangential stretch forming and simple stretch forming are quite similar to each other.

(a) True

(b) False

This question was addressed to me in a national level competition.

Query is from Stretch Forming topic in division Miscellaneous Forming Processes of Casting-Forming-Welding II

Answer 1

The correct option is (b) False

The best I can explain: Tangential stretch forming is very different from simple stretch forming. However, the purpose is same. In tangential stretch forming, the metal sheet is gripped from two opposite ends. The main difference to the simple stretch forming is that the form block and gripping jaws both are movable in this process.
